Abstract

Disclosed is a process for the preparation of electrostatographic toner particles having improved mechanical properties, controlled particle size, and appropriate size distribution by accomplishing molecular orientation of glassy, brittle, semi-cyrstalline, low-molecuIarweight polymers. The molecular orientation of these polymers, which is caused by the extrusion of polymer fibers or films, results in more flexible polymers, increases their yield stress, and their mechanical fatigue. In a specific embodiment, the process involves forming a blend of the polymeric
